IMPROVEMENT lN APPARATUS FOR DEODORIZING GASES FROM RENDERlNG-TANKS.

Specification forming part of Letters Patent No. 194,194, dated August14, 1877; application filed May 12, 1877.

To all whom it may concern: 7

Be it known that I, CHARLES JOSEPH Tno'r- TEE, of Chicago, in the countyof Cook and State .of Illinois, have invented a new and ImprovedDeodorizing Apparatus,'of which 7 the following is a specification:

Figure l is a vertical central section of my improved apparatus, takenon line 00 a; in Fig.

2. Fig. 2 is a plan view.

pipe, I), is screwed into the opposite side of the drum, a shortdistance from the lower head. A hand-hole, c, is made in the upper head,and is stopped by a suitable cover, d. A pipe, e, extends through theupper head, for conveying away the gases after they are treated in theapparatus.

To a condenser connected with a sewer, and

having a sewer-trap for preventing back flow of gas, a funnel, f, isprovided, for introducing the deodorizing agent; and g is an aircock forthe escape of air from the apparatus.

The manner of using the apparatus is as follows: The drum A is filledwith a suitable deodorizing liquid up to the pipe b, and the pipe to,being connected with the cooking or rendering apparatus, conveys the gasand vapor from thence to the drum A, where they are forced through thedeodorizing liquid contained in the drum. and escape through the pipe 0to a condenser connected with the sewer, being freed from disagreeablesmell.

The liquid which condenses in the apparatus is conveyed away by the pipeb.

The deodorizing liquid is introduced, whenever necessary, through thefunnel f, the valve 9 being opened to facilitate the operation bypermitting the air contained in the drum A to escape as the liquid ispoured in. After introducing the liquid the valve g is closed, and thefunnelfis stopped by a plug or a suitable valve, and when the apparatusrequires cleaning the handhole cover is removed.

The escape-pipe 0 may be connected with a sewer, when the fumes of thedeodorizing liquid which escape with the gas may, or the gas may, beconducted to the furnace of the cooking or rendering apparatus, when itwill be consumed. 7

Having thus described my invention, I claim as new and desire to secureby Letters Patent- In rendering animal matter, the method of absorbingthe evolved noxious gases in a liquid deod'orizer, as shown anddescribed. 7
